University of Michigan researchers are investigating a radical new design for cargo ships that would eliminate ballast tanks, the water-filled compartments that enable non-native creatures to sneak ...

Through a lot of expensive and dangerous trial-and-error over multiple centuries -- sometimes resulting in shipwrecks you still can explore today-- humans have pretty ...

TRAVERSE CITY, Mich. (AP) - After decades of delay, government officials are beginning to crack down on cargo ships that allow foreign invasive species to hitchhike to U.S. waters, where they have ...

The BWM Convention amendments formalizing the implementation schedule for the D-2 standard are now in force. Amendments to an international treaty aimed at preventing the spread of potentially ...

Ships have always required ballast to operate successfully and safely. For millennia, ships carried solid ballast in the form of rocks, sand, roof tiles, and many other heavy materials. From the 1880s ...

In the battle against invasive species, giant commercial ships are fighting on the front lines. But even when they follow the rules, one of their best weapons is coming up short, marine biologists ...

A new robot for inspecting ballast water tanks on board ships is being developed by a Dutch-German partnership including the University of Twente. The robot is able to move independently along rails ...

There are few other topics gathering more attention than ballast water exchange, as the chorus of environmental damage from the scientific community and howls of reform from the legislative community ...

Untreated ballast water discharge from ships can spread living organisms and even pathogens across the world thereby introducing non-native or invasive species into the local environment. Scientists ...

In order to maintain a consistent buoyancy as their cargo loads change, ocean-going ships pump seawater in and out of their ballast tanks. Needless to say, that salty water isn't exactly the ...

This chapter identifies various methods of treating ballast water that are safe, practicable, technically feasible, cost-effective, and environmentally acceptable. The main focus is on treatment ...
